With its high strength, durability, and diverse surface treatment characteristics, metal sheets have become the core materials in modern construction, industrial manufacturing, transportation facilities, and other fields. This article will systematically analyze the application scenarios and core advantages of mainstream metal sheets to provide references for industry selection.

I. Comprehensive Application Advantages of Color-coated Aluminum Sheets

By integrating the aluminum substrate and organic coating technology, color-coated aluminum sheets possess both the strength of metal and the decorative properties of the surface, and have now become a star material in the construction industry. In the field of industrial architecture, they are widely used in the exterior walls and roofing systems of airport terminals, stadiums, and industrial plants, ensuring the long - term durability requirements of buildings with a weather resistance of over 25 years.

This material has three core characteristics:

1. Environmental Adaptability: The fluorocarbon coating technology enables it to resist acid rain, ultraviolet rays, and temperature - difference deformation, and its fire - resistance rating reaches the A2 standard.

2. Engineering Economy: Its weight is only one - third of that of steel sheets, reducing the load on building structures and increasing construction efficiency by 40%.

3. Multi - scenario Expansion: In the household appliance manufacturing industry, it is used for refrigerator shells and air - conditioning ventilation systems; in the automotive industry, it is applied in scenarios such as oil pans and interior parts.

Market data shows that the annual production capacity of domestic color - coated aluminum sheets has exceeded 300,000 tons, and driven by green building policies, the compound annual growth rate remains above 12%.

 

II. Functional Differentiation of Decorative Metal Sheets

1. Aluminum Gusset Plate System: Standard plates with a thickness of 0.6 - 1.2mm are formed through anodizing treatment. Their fire - and moisture - proof performance meets the GB 8624 standard, and they are mainly used for suspended ceilings in commercial spaces and wall surfaces in clean workshops.

2. Mirror Stainless Steel Plate: Made of 304 stainless steel with 8K polishing technology, its surface hardness can reach HV500, making it suitable for high - end hotel bathroom spaces and the construction of antibacterial environments in medical institutions.

 

III. Innovative Applications of Industrial Special Metal Sheets

1. Tin Plate System: Food - grade tin - plated sheets (MR - T4 material) with a thickness controlled between 0.15 - 0.30mm have three - times higher corrosion resistance and are mainly used for canned food packaging and pharmaceutical sealed containers.

2. Nickel - based Alloy Plate: In the petrochemical industry, Hastelloy plates can withstand temperatures up to 1200°C and are used for reactor linings and flue gas treatment systems.

3. Cold - rolled Steel Plate: The automotive industry uses DC04/DC06 grade cold - rolled sheets. Through a stamping strength of up to 600MPa, vehicle body lightweighting is achieved, and the usage per vehicle exceeds 400kg.

 

IV. Technological Breakthroughs in New Composite Sheets

Through the trapezoidal cross - section design, the load - bearing capacity of 18mm - thick corrugated steel sheets is increased to 200kg/m². Combined with the sandwich structure of polyurethane foam core, the building's sound - insulation index reaches 55dB, and it has been widely used in the enclosure systems of logistics warehouses and transportation hubs.

With the iteration of surface treatment technology, metal sheets are transforming from basic building materials to functional and intelligent materials. The application of innovative processes such as nano - coatings and self - cleaning coatings will drive the industry into a new development stage of high performance and low maintenance.
